RESILIENT WHEEL Specification of Letters Patent.

Patented Dec. 5, 1905.

Application filed April 19, 1904:. Serial No. 203,907.

To a/ZZ whom it may concern:

Be it known that I, IRMA GUIOT, a citizen of France, and aresident of Puyricard, Bouchesdu-Rhne, France, have invented certain new and useful Improvements in Resilient Wheels, of which the following is a specification.

This invention has for its object a resilient tire for all kinds of vehicles.

Figure l is an elevation of a Wheel ritted with this improved resilient tire; Fig. 2, an elevation of a part of the rubber surrounding the external rim; Fig. 3, an elevation of one of the pieces of solid india-rubber forming a spring. Fig. 4 is a section of the tire on the line Z Z of Fig. 1. Fig. 5 is a section of the spoke-holding rim or felly. Fig. 6 is a section of the concentric second rim, which rim holds the tread or tire.

The wheel is provided on each side of its ordinary wood rim with two steel rings A, riveted to said rim, and which increase its diameter in such a way as to leave a circular space intend ed for receiving arc-shaped' pieces of india-rubber B, forming springs. These pieces B, of india-rubber, are fixed to the two rings A by rivets C,which pass through them. A wheel-rim D, of steel and of slightly larger diameter than the wheel and concentric with the ordinary rim, receives in an internal circular space the ends of the india-rubber pieces, which are fixed by rivets E. The same rim D is surrounded externally by a band F Or cushion of solid rubber, which is fixed to the said rim by rivets G.

The india-rubber pieces B,forming a spring, and the india-rubber F, forming the tread or tire, are made in a particular manner. The

parts H, intended to receive the rivets, are of vulcanized india-rubber or ebonite, while the other parts are of ordinaryexihle india-rubber in order to avoid any tearing. The holes intended to receive the rivets are also provided with sockets I, of copper or the like, in the form of collars, so as to avoid wear which might arise from friction against the rivets.

As regards the application of this resilient tire to a bicycle, Fig. 5 shows a section of the ordinary spoke-holding rim, and Fig. 6 a section of the second concentric rim, which carries the tread or india-rubber tire. The india-rubber pieces B, forming the springs, are of smaller dimensions, placed between the two rims and riveted in the manner stated.

The number and dimensions of the indiarubber blocks B, forming the springs, may

`vary according to the weight which it is in'- yconnected thereto, solid india-rubber blocks in the form of an arc Of a circleforming springs and having parts of vulcanized indiarubber or ebonite adapted to receive the rivets for fixing them to the rings.

In Awitness whereof I have hereunto set my hand in presence of two subscribing witnesses.

IRMA GUIOT.
